This Animation Praxinoscope Kit allows you to convert a reel of images into an animation via a spinning disc with mirrors reflecting the images on the outskirts of the disc through the viewfinder. As the disc spins, the viewer sees images in rapid succession which the brain processes as an animation! Includes pre-made discs as well as blank discs for creating your own animations. Measures 13 cm tall when assembled! Batteries & LED included!
